Carbon Fiber Composite Design Guide

Applications for High Specific Stiffness Graphite composites are ideally suited for applications where high stiffness and low weight is required. Most metals used for structural applications have very similar specific stiffness, which is around 100 x 10^6 psi. If an

Graphite Grades for Electrical Discharge Machining (EDM)

GRAPHITE OPPER graphite has a metal removal rate 2 times higher than copper with lower electrode wear graphite does not melt but sublimes at 3,400 C, providing much greater wear resistance than the low melting point of copper graphite has a low density so

Nanoindentation of flexible graphite: experimental

Again, such difference is due to the high porosity of flexible graphite, making it highly deformable with the elastic recovery which is very useful for applications as seals and gaskets. Finally, the indentation loading-unloading cycles shown in Figure 3 presented small flat tops, neglected in the modelling such as that shown in Figure 7, whose lengths correspond to creep.

A Raman spectroscopic investigation of graphite oxide

2012/9/25Graphene sheets that are now routinely obtained by the exfoliation/reduction of graphite oxide exhibit Raman spectra unlike traditional graphene systems. The general attributes of the Raman spectra of these 'wrinkled graphene' are first reaffirmed by evaluating the spectra of samples prepared by seven different exfoliation-reduction methods.

Facile and economical exfoliation of graphite for mass

We simulate a micromechanical exfoliation process to design a simple but effective and low-cost strategy for mass production of high-quality graphene sheets by planetary milling with oxalic acid.The selective carboxylation enables oxalic acid molecules to adhere to the edge and defects of graphite like a Scotch tape and plays a crucial role in the non-destructive exfoliation.
